The correct option is B 50
wt.ofHCl=Normality×Eq.wt×volume1000wt.ofHCl=0.1×36.55wt.ofHCl=0.73 gm

Metal carbonate neutralized completely in HCl means number of moles of metal carbonate is equal to No.of moles of HCl.

mol.wtofmetalcarbonate=mol.wtofHCl×wt.ofmetalcarbonatewt.ofHCl

mol.wtofmetalcarbonate=36.5×10.73mol.wtofmetalcarbonate=50.
